Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
kontact left running over night.  On trying to send an email (by hitting the send button in the composer window), the window is fadded and the email to be sent is added to the outbox, but does not get sent.  I hit the x button to close the email and was presented with a 'save draft' 'discard' 'cancel' dialog window.  I selected cancel and then kontact crashed.  Upon restarting kontact, I was given the 'kontact already running' warning window to which I responded 'start anyway'.  The email was still in the out box and sent with out error in the restarted kontact.

This has happened before (once ever other week), but I can not reliabley reproduce it.  I have a hunch that it is related to kwallet interactions.  In all the cases that it has crashed I have first started kopete and opened kwallet.  The wallet is still open when I attempted to send the email.
